The welding process that uses a non-consumable electrode and a shielding gas is referred to as?

The welding process that utilizes a non-consumable electrode and employs a shielding gas is known as Gas Tungsten Arc Welding (GTAW). In this method, the electrode is made of tungsten, which does not melt during the welding process. Instead, the arc generated between the tungsten electrode and the workpiece creates the necessary heat to melt and fuse the metals being welded together.

GTAW is known for producing high-quality welds and is often used for applications where precision and cleanliness are important, such as in aluminum and stainless steel fabrication. The shielding gas, typically argon or helium, protects the molten weld pool from contamination by the atmosphere, ensuring a cleaner and stronger weld.

The other methods referenced, such as MIG (Metal Inert Gas) and GMAW (Gas Metal Arc Welding), utilize a consumable electrode which melts and becomes part of the weld, and while they may also use shielding gas, they do not align with the description of using a non-consumable electrode. FCAW (Flux-Cored Arc Welding) employs a tubular wire that contains flux, which does not fit the criteria specified either. Therefore, focusing specifically on the process that includes a non-consumable electrode and shielding gas, GTAW is clearly
